On a Tuesday morning, an email lands in the inbox.
It appears to come from the CEO. The sender name checks out. The wording sounds right. Even the signature feels authentic.
"Hey — can you help me with something quickly? I'm tied up in back-to-back meetings. I need you to process a vendor payment. I'll explain later."
The new hire stops and thinks.
They've only been there four days. They're still learning the workflow. They don't know what normal looks like yet, and they definitely don't want to be the person who challenges the CEO during their first week.
So they do what seems helpful and move forward.
And in that moment, the damage is already underway.
Why the first week is the highest-risk week
Each spring, companies welcome a fresh group of employees, often recent graduates and summer interns stepping into their first professional roles. For businesses, it's onboarding season. For attackers, it's an opening.
Keepnet Lab's 2025 New Hires Phishing Susceptibility Report found that CEO impersonation emails are 45% more likely to work on new hires than on experienced staff.
Cybercriminals don't focus on your most experienced team members. They target the people still learning the culture, the process, and the unwritten rules because the beginning is when uncertainty is highest.
A new employee may not know what a legitimate request looks like. They may not know how the CEO normally communicates. They haven't had time to build instincts or confidence, and attackers exploit that uncertainty.
But the issue isn't the new hire. The biggest risk isn't a careless employee. It's the one who is trying hard to be helpful.
If you lead a business, you probably already know exactly who on your team would answer first.
The real weakness isn't training. It's the system.
Think back to that employee's first day.
The laptop wasn't ready. Access wasn't fully configured. The email account was still being built. They borrowed a coworker's login to check something fast. They saved a file to their local drive because the shared folder wasn't available. They used a personal phone to look up a client number because it was quicker.
None of that felt dangerous. It felt efficient. It felt like getting through a busy first day and making things work.
But during that first week, before every control is in place, several quiet problems start to form. Shared credentials create accounts no one can fully track, files sit outside backup systems, personal devices touch company data, and no one has explained what to do when something seems suspicious.
The same Keepnet report found that new employees are 44% more susceptible to phishing than seasoned staff. That difference doesn't come from carelessness. It comes from disorder. When onboarding is messy, security becomes an afterthought. That's the environment a phishing email is counting on.
The attack didn't create the weakness. The first day did.
What a secure first day should look like
Solving this doesn't require a long security lecture on day one. It requires three things to be in place before the employee ever walks in.
1. Their access is ready, not improvised.
That means the laptop is set up, credentials are created, and permissions are clearly assigned. No borrowed logins, no temporary fixes, and no "we'll handle that later this week."
2. They understand what a normal request looks like in your company.
This can be a simple 10-minute conversation. Does the CEO ever email about payments? Does anyone? What should they do if a message feels off? This isn't formal training; it's basic orientation.
3. They have a safe place to ask questions.
The employee who hesitated before clicking that email probably would have checked with someone if they'd known who to ask. Most first-week mistakes happen quietly because new hires don't want to appear inexperienced.
Give them a person. Give them a process.
Most security failures don't happen because someone intentionally breaks the rules. They happen because the rules haven't been made clear yet.
Maybe your onboarding process is already strong. Maybe your team is small enough that the first few days feel more personal than procedural. But if you've ever watched a new hire improvise through week one — or if you're planning to bring someone on this spring — it's worth addressing it before that Tuesday email shows up.
